Under some not quite clear conditions, NFS fails to use its unlink workaround to rename a file to ".nfsXYZ". The problem has been reproduced with the GAWK testext.awk testcase. To workaround this in Cygwin, we now call try_to_bin on NFS, too. For some reason NFS doesn't fail to rename the .cygXYZ file to .nfsXYZ after this Cygwin rename. Fix comment in unlink_nt accordingly. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
